I still have them in my little boat, but moved to Odyssey 2150 AGM type batteries in my bigger boat. Uncle Dave Laveycraft 2750 Ilmor 710 Laveycraft 20.8 Sebring 406 SB |
I used to have two blue tops in mine, for awhile I thought they were both bad because they would barely turn the motor over. That's when I bought the red top for its higher cranking amps, same thing. Then I changed the battery cabling out from 2 awg to 1/0 (or maybe 2/0, I can't remember for sure) and that made a huge difference. Motor turns right over and fires right up now, great improvement.
Keep in mind there are two types of blue tops, one a dual-purpose and one a strictly deep cycle that iirc they said not to use for starting on optima's website. But it has been awhile since I looked so that may have changed. |

My experience with a blue top Optima in my flat bottom is beyond excellent. I purchased that battery in 1998 and the boat sits in my garage all winter long, when it is time to use it and I put the charger on it, it always shows a full charge. I can't believe that it is still good after 10 years, but that certainly justifies the added cost. That boat has a 12.5:1 compression Big Block Chevy, so it isn't easy to start. I think in this case you do get what you pay for. |
Just bought Optimas this summer...happy so far!

I think the reason to buy Optimas is because they stand up to the violence of high speed boating better than standard lead plate batteries. If you are sitting in a lab, like consumer reports, you should not see an advantage. If you slam around at high speed in an offshore boat, I think you will see a difference: they have certainly lasted much, much better for me. YMMV.

DUDE, you got the freak of nature battery, just out of curosity, do you have amps and a bbig stereo. I am a believer that the big stereos kill batteries, thus why I replace every two years, rathe rthey need it or not. Just like impellers, I replace those every two also. :ernaehrung004:
The Flat Bottom music comes from the 700hp engine. |

The Fountain does have a big amp, but I rarely turn on the stereo.
The Flat Bottom music comes from the 700hp engine. two 4300 watt amps,1 1800 watt. 2 12 inch subs 4 10 inch subs and about 10 5 in speakers.. And i just use one of the batteries most of the time ....Optima Blue. it was in my other boat for a couple years too! |
I changed from an Optima blue top to a smaller Odyessy 1200.
My boat trims, and starts faster from a smaller battery. My last Odyessy in my street car lasted 8 years. I also saw a few optima failures in race boats this summer. |
